Turf JS is not effectively generating Objects

Exploring the functionality of the helper function called turf.point()

const feature = turfHelpers.point(coords, properties, { id: properties.id });

The structure of the variable properties is as follows:

properties = {
  id: 1,
  thisWorks: 'no problem'
  foo: {
    thisDoesntWork: 'this is a problem'
    }
  }

Upon creating the feature using turfHelpers.point(), the object is altered. The nested object is no longer recognized as an object, but instead gets converted to a string...

Therefore, now features.properties appears like this:

{
  id: 1,
  thisWorks: 'no problem'
  foo: "{
    thisDoesntWork: 'this is a problem'
  }"
}

Subsequently, it becomes impossible to access

feature.properties.foo.thisDoesntWork
since it has been turned into a string... What could be the reason for this behavior exhibited by turf.js?

Answer №1

Let's transform the query into a runnable format.

const turfHelpers = turf.helpers;
const coordinates = [100, 14];
const attributes = {
  id: 1,
  thisWorks: 'no issue',
  foo: {
    thisDoesntWork: 'there is an error'
  }
};

var feature1 = turfHelpers.point(coordinates, attributes, {
  id: attributes.id
});

// Display on console
console.log(feature1.properties); //looks fine

console.log(feature1.properties.foo); //still good

console.log(feature1.properties.foo.thisDoesntWork); //all good
<script src="https://cdnjs.cloudflare.com/ajax/libs/Turf.js/5.1.5/turf.min.js"></script>

This setup should be useful for generating discussions that can lead to a resolution.
